Further, when the bumper is mounted on the vehicle body, the guide pin is fitted and positioned in a substantially U-shaped locking groove formed continuously below the inner periphery of the large diameter hole of the bumper mounting hole. Since the plate-shaped frame is sandwiched between the bumper and the bumper holding cone by the urging force of the spring, the bumper can be securely fixed to the vehicle body.

1. A large-diameter hole portion having an inner diameter through which a bumper holding cone supported by a guide pin protruding from the rear surface of a bumper can pass through a bumper mounting surface of a plate-shaped frame of an automatic guided vehicle, and the large-diameter hole. A substantially U-shaped locking groove having a width that allows the guide pin to be continuously inserted into an inner peripheral lower portion of the portion; a bumper holding cone having an end face closer to a back surface of the bumper; The outer peripheral surface is conically expanded toward an end surface farther from the outer peripheral surface, and a guide hole slidably fitted to the guide pin is formed in a central axial direction and mounted on the guide pin. The spring is urged toward the back surface of the bumper by a spring, and the guide pin is inserted into the large-diameter hole portion of the bumper mounting hole of the plate-like frame from the bumper mounting surface side together with the bumper holding cone, and the bumper rear surface is bumped. The outer peripheral surface of the bumper holding cone is guided by the inner peripheral edge of the large-diameter hole portion of the bumper mounting hole by pushing down the bumper at the position where the bumper is brought into contact with the mounting surface and moving the guide pin into the locking groove. A bumper for an automatic guided vehicle, wherein the bumper is configured to ride around the periphery of the locking groove on the back side against the elastic force of the spring and to sandwich the plate-shaped frame between the bumper and the bumper holding cone. Mounting structure.
